Amr, you must know that I am a book-lover as well as a coin & stamp collector! Some of these older books are just as beautiful to me as an uncirculated Morgan Dollar or a mint stamp from some exotic tropical paradise!

Old books are something I'm interested in possibly collecting some day. Old maps too. I love maps.

I love old books, especially the cover and the way of writting. Some times the include maps or sketches....and of course the content...this what it makes it realy valuable
